The uncle of Fawzi al-Juneidi, a Palestinian boy detained by the Israeli authorities last week, also attended the rally on an invitation by the organizers.

Juneidi, 16, has become a symbol of ongoing Palestinian protests against Trump’s decision on Dec. 6.

Grand National Assembly of Turkey Administrator Ahmet Gundogdu, Republican People's Party (CHP) Deputy Chairman Veli Agbaba and other deputies also attended the rally.

The rally started with the national anthem, followed by a performance and recitation of the Quran.

Jerusalem remains at the heart of the Israel-Palestine conflict, with Palestinians hoping that East Jerusalem -- now occupied by Israel -- might eventually serve as the capital of a future Palestinian state.
